Source Naturals Wellness Oil of Oregano

Not only does oil of oregano protect you when you feel a cold coming on, it’s also an effective topical treatment for cuts and insect bites.

The ancient Greeks depended on oil of oregano for its antiviral, antibacterial and antifungal powers, and multiple studies have since proven its effectiveness. Make sure the oil you’re using has at least a 70 percent concentration of the active ingredient carvacrol, like this Wellness formula from Source Naturals. $20 for a half-ounce bottle at www.sourcenaturals.com.
